Question

我想在自动填充视图中使用google place API。我有来自开发者控制台的android和浏览器密钥。但是当我尝试这些键时它返回空响应的API。

logcat的：

我的代码：

 class GetPlaces extends AsyncTask<String, Void, ArrayList<String>> {

        private ArrayAdapter<String> adapter;

        @Override          
        protected ArrayList<String> doInBackground(String... args) {
            ArrayList<String> predictionsArr = new ArrayList<String>();

            try {
                URL googlePlaces = new URL(                         
                        "https://maps.googleapis.com/maps/api/place/autocomplete/json?input="
                                + URLEncoder.encode(args[0].toString(),
                                "UTF-8")
                                + "&types=geocode&language=en&sensor=true&key=mykey");


                URLConnection tc = googlePlaces.openConnection();

                BufferedReader in = new BufferedReader(
                        new InputStreamReader(tc.getInputStream()));

                String line;
                StringBuffer sb = new StringBuffer();

                while ((line = in.readLine()) != null) {
                    sb.append(line);
                }

                JSONObject predictions = new JSONObject(sb.toString());

                JSONArray ja = new JSONArray(predictions
                        .getString("predictions"));

                for (int i = 0; i < ja.length(); i++) {
                    JSONObject jo = (JSONObject) ja.get(i);
                    // add each entry to our array
                    predictionsArr.add(jo.getString("description"));
                }
            } catch (IOException e) {

            } catch (JSONException e) {

            }

            return predictionsArr;

        }



        @Override
        protected void onPostExecute(ArrayList<String> result) {
            // put all the information in the list view to display
            Log.d("YourApp", "onPostExecute : " + result.size());
            // update the adapter
            adapter = new ArrayAdapter<String>(mActivity,
                    R.layout.simple_list_item);// show the list view as texts
            // attach the adapter to listView
            listViewSearch.setAdapter(adapter);

            for (String string : result) {
                adapter.add(string);
                adapter.notifyDataSetChanged();

            }

        }

    }

并在onpostexecute日志中：

D/YourApp: onPostExecute : 0

我是google places api的新用户，请帮我找出错误。

Answer 1

我认为您没有使用正确的API密钥。按照this guide正确启用Android版Places API。而且sample由Google正确实施Place Auto完成。

Answer 2

除使用Android Key外，请使用Web服务密钥。并从开发人员控制台启用它。
